Summary

Description

NASA needs narrow linewidth lasers in the 1.5 or 2 micron wavelength regime for coherent Lidar applications. The laser should be tunable by several nm and frequency modulated by 5GHz. Princeton Optronics has developed ultra-stable narrow linewidth diode pumped solid state lasers at 1550nm and has demonstrated frequency modulation with such lasers. In this SBIR, we propose to develop a Tm:YAG material based diode pumped solid state laser with a narrow line width which would be tunable and capable of frequency modulation by 5GHz. By the end of the SBIR program we plan to develop a prototype 2 micron laser which is tunable and has very narrow linewidth in a small package. The package with the device would be space qualified and commercialized after development.
